실험 절차
Dissolve the tert-butyl 5-bromo-3(R)-(hydroxymethyl)-8-methoxy-3,4-dihydroisoquinoline-2(1H)-carboxylate (710 mg, 0.0019 mol) in dimethylsulfoxide (2.00 mL) and cool to 0° C. Add triethylamine (1.06 mL, 0.00763 mol) and sulfur trioxide-pyridine complex (0.607 g, 0.00381 mol). Warm to room temperature over one hour. Dilute diethyl ether (100 mL) and extract (3×25 mL) with 5% aqueous citric acid, (1×25 mL) saturated aqueous sodium chloride, and dry over magnesium sulfate. Concentrate the filtrate to give the desired product (687 mg, 94%) as an off-white semi-solid.
